The difference between using `:` and `::` in Blade component attributes is:
1. `:` (colon): This is used to pass a PHP expression or variable as the value of an attribute. It tells Blade to evaluate the expression and use the resulting value as the attribute value.
Example:
html
<x-button :type="$buttonType" :text="$buttonText" />
In this case, `$buttonType` and `$buttonText` are PHP variables that will be evaluated and passed as the `type` and `text` attributes of the `
2. `::`: This is used to escape an attribute value so that Blade does not treat it as a PHP expression. This is useful when you need to pass a string that contains Blade syntax, such as when using JavaScript frameworks that also use curly braces.
Example:
html
<x-button ::class="{ 'btn-danger': isDeleting }" />
In this case, the `class` attribute value `{ 'btn-danger': isDeleting }` will be passed to the component as a literal string, without Blade trying to evaluate it as a PHP expression.
The double colon `::` tells Blade to treat the entire attribute value as a literal string, rather than trying to evaluate it as a PHP expression.
In summary:
- `:` is used to pass dynamic, evaluated values as component attributes
- `::` is used to escape attribute values so that Blade does not try to evaluate them as PHP expressions
This allows you to more easily integrate Blade components with JavaScript frameworks that use similar syntax, while still being able to pass dynamic data to the components.
